SPECIFIQAT'IQN forming part of Letters Patent No. 315.147, dated April 7, 1885. Application filed Jnly 25, 1884. (No model.)

T0 on whom it may concern.-

Be it known that we, WILLIAM A. KONE MAN and HIRAM H. ScovILLE, of Chicago, county of Cook, State of Illinois, have invented certain new and useful Improvements in Endless-Belt Ore Concentrating or Vanning Machines; and that we hereby declare the following to be a true and correct description ofthe same.

Heretofore in vanning-machines the materials have been agitated while partly suspended in flowing water. This agitation has been confined to end or side shake of the vanningsurface over which the mixture of ore and gangue was deposited.

According to physical laws, shaking in substantially horizontal directions tends to settle and stratify the material according to specific gravities. but will not so separate them that the material of one gravity may readily pass offin one direction, and material of another gravity pass off in another direction; bntsuch complete separation is required of a vanningmachine, because the ore is expected to discharge over one side or end of the table while the sand passes over the opposite side or end.

To obviate the effect of settling in preventing a complete separation according to gravities, we have given to the vanning-surface a vertical shake,whereby the tendency to settle is counteracted and the stratification according to gravity is facilitated. The effect of the vertical shake is enhanced by making the upward movement at a different speed from the downward movement.

Another physical law is made available to facilitate the complete separation of the materials, and that-is the law which causes bodies in contact to adhere. Thus when the vanningsurface is caused to fall in vertical plane the material which is in contact with said surface will be affected more than that which is immersed in the mobile fluid above, and the heavier material will be affected more than the lighter material.

. It is well known that the difference in specific gravity" between the OIOI and its gangue varies greatly, and it is plain that the maximum efl'ect of agitation will'be attained when the quantity and speed of the agitation are inclination of belt-as to meet such conditions and requirements of metal-bearing ores as are due to the great difference in specific gravity between the metallic portion and the gangue, as well as on account of the greater or less de gree to which such ores are oxidized ordecomposed, and the quantity of metal contained in them having a tendency to float in a water current; also, to enable the regulation of motion and speed to meet the different requirements in an ore owing to the difference in fineness to which it has been reduced.

In the following specification, and in the drawings attached thereto, we have set out the employment of a revolving cam to produce the gradual lift and sudden drop of the vanning-surface; but it is evident that this result may be produced bya cam located differently from that shown, or by a stationary cam-track, or by other known mechanical expedients. In the same way the fulcrums of the arms which vibrate the van ning'surface are shown with adjustingscrews; but it is evident that said fulcrums may be adjusted by means of wedges and other known devices.

We have employed acrank to produce the horizontal vibration of the vanning-surface; but the same vibration has been produced by cranks arranged in various ways, and by cams; therefore we do not desire to be limited to these particular devices, as shown herein.

Referring to the drawings, which are part and parcel of this specification, Figure 1 rep resents a side elevation of our apparatus. Fig. 2 represents a longitudinal section. Fig. 3 represents a downward plan or view. Fig. 4 represents a longitudinal section through the slide on the radial arm. Fig. 5 represents an enlarged view of cam and stirrup, its connectionwith the radial arm and radial armbelt. Fig. 6. represents a view of belt-regulating adjustment. Fig. 7 represents a sec- ICO tion through frame and guide, showing sliding l fitted in the radial arm S and raised, lowered,

adjustment of box 1' at the tail end of machine. Figs. 8 and 9 are detail elevations of mounting and driving gear for be1t-wipers. Figs. 10 and 11 are section and elevation of vibrating-arm mounting. Fig. 12 is a perspective of crank and cam. Fig. 13 is a series of diagrams of the movements of the table.

A represents the frame of the machine.

B represents the carrier-frame suspended from the top of the frame A by rods or cords a, so that it may swing or oscillate.

E is a drum at the head of the carrier-frame, journaled in boxes E, attached to the frame B.

The caps of said boxes extend downward, and

wiping-rolls coincidently with the belt travel.

G is a drum at the tail of the frame, journaled in a sliding adjustable box, i, on each side of the frame B. These boxes are planed and fitted I to grooved ways H in frame, as shown in Fig. 7, and are thrust out or drawn in to put the proper tension on the-traveling belt by screws h h simultaneously operated by means of a socket-wrench on a transverse shaft, i,which carries the bevel or miter wheels These wheels are fastened to the shaft 1" by set-screws, instead of keys, in order that either end of the drum maybe adjusted with out moving the other end to compensate for uneven stretch of the belt.

D is a wide endless belt passing around drums E G, and supported intermediately by rollers g 9, whose bearings are in the frame 13, and is given constant motion around said drums by means of the worm j,which itself is given any speed required by the cone-pulleys V V, their belt V, and chain-wheel '0 on the shaft of cone-pulley V and chain-wheel v on the worm j, around which passes chain o Motion is given the upper cone-pulley, V, by

driving-shaftI 7c and pulley K. The shaft is also carries a cone-pulley, L, from which a belt, L, drives the cam and crank shaft Z, upon which is cone-pulley M, corresponding to cone-pulley L. b Upon the extreme ends of the shaftl are cranks P, and immediately inside the frame A, upon which the shaft is journaled, is the cam N, and between cam N and cone-pulley Ma balance-wheel, 1', is keyed to shaft Z, to impart steadiness to the motion. Around cam N'is a yoke, O, which is held in position by bearings m m on the frame A.

To one end of yoke O a connecting-rod, T, is attached, and the other end of connectingrod T is pivoted on the link-block S,which is s may be shifted without changing the angular position of the arm S at the moment, we provide said arm with a longitudinal slot curved on a radius equal to the length between centers of the connectingrod T; and in order to permit said block to be longitudinally adjustable by means of the screw 8 we fit to said curved slot a slide, S and provide the block S with a cylindrical jointpin, s*,whicl1 passes through said slide, and is adapted at its extremity to form thepivot forthe connecting-rod joint. The screw 8 passes through said block S, and at its extremity it revolves in a bearing, S, which has a pivotal connection with the arm S, and also supports the bearing for the bevel-wheel s and sprocket t.

P P are cranks on the ends of shaft Z, to

which are attached connectingrods n n, the other ends of said rods n n being attached to the upper ends of vibrating levers R R,which are fulcrumed on movable blocks R and at their lower ends pivoted to the carrier-frame B.

y is a shaft central with levers R and journaled upon frame A. This shaft has upon its extreme ends, bevel or miter wheels 2, meshing into bevel or miter wheels y on the end of screws R, which raise and lower the pivotal boxes R in levers B when the screws are r0 tated, which is accomplished by a chain, 0 passing over chain'wheel c and thence down to within easy reach of the operator,where it passes round a similar chain wheel, 0 on a shaft, 0", which is turned by the assistant to revolve the screws R and raise or lower the pivotal blocks R in the levers R R, as desired, to give more or less vibration to the carrierframe B.

t is an idler-chain passing over the idlerchain wheel t journaled on the shaft'u, and the chain-wheel t on the shaft 14 to keep the chain t always of proper length during changes of position of said arm. a is a shaft journaled on frame A, and provided with the radial arm S and the counterbalancing-arm b, upon which is counter-weight W, and the arms U U, from the extremities of which the head of the carrier-frame B is suspended by means of the rods or cords a, which are attached to the carrier-frame B by brackets 12. These ropes are provided with turn-buckles b", to keep the carrier-frame in perfect level transversely.

p p are bracket-bearings fastened to both sides of carrier-frame B, and the lower ends of the vibrating arms R R are journaled on them.

B is a distributing or spreading box for ICO act motion under which the ore will give the The finer the ore and the more completely delowered to adjust the frame B and its belt D prevented from revolving, except when reproper method of pnlverization, is fed onto the table.

than-the point at which the ore is being disthe belt L on the cone-pulleys M L.

grams ofthe various combinations of motion the ore to be concentrated. Z is a tailings-l box or sluice. The rear end of the frame B does not have any lift and drop in its'operation'; therefore the rear, end of said frame is supported by cords a, the upper ends whereof are wound upon drums d on the shaft e; but the rear end of said frame may be raised or as to pitch toward the tail by turning said shaft. This may be accomplished at will by means of a chain, c, which passes over a sprocket-wheel, 0 on said shaft 6 and under a similar wheel on the shaft 6. The shaftc is also provided with a counter-balancing arm, 6 and weight W, adjustable thereon so that the carrier may be easily raised or lowered. The shafts a, u, and e are each provided with ratchets f and pawls f, whereby they maybe quired by the operator; but adjustments may be changed as required without stopping the machine.

The operation of the machine, one of which we now have in successful use, demonstrating all parts as herein set forth, is as follows: The ore to be operated upon, after first having been pulverized to a suitable degree of finenesssay from forty to eighty mesh-by any the revolving belt D by means of a suitable distributer, B at a point varying from two to four feet distant from the drum E or head of Sufficient water is introduced with the ore to cause the same to flow quite freely, and fresh water is distributed on the table through a finely-perforated pipe, F, atapoint higher up and toward the head of'the table tributed. It is now necessary to find the ex cleanest concentrates. The stroke oscillation of the frame B can be varied from one-half inch to four inches by raising or lowering pivoting slides R on screw R, as described.

composed it is the less the stroke and the greater the speed of stroke required. The speed is regulated by shifting the position of The height of the lift and drop affording the best' results is now tested. It varies from fiveeighths of an inch to one and one-quarter of an inch, the same rule holding good as with the strokethe finer and more decomposed the ore the less the lift and drop. It is necessary to describe the action of the table on ores by this combination of a slow forward stroke with an upward lift at the same ratio of speed, together with a quick backward stroke and a sharp drop of the forward orhigher end of the frame. The result is a triangular motion or movement at any certain point on the belt,varying in shape with the adjustment of the frame. As illustrations, three combinations are shown in Fig. 13, wherein are diabelt travel.

of the swinging table and belt, 1 representing the extreme with a long stroke and a short 'lift, 2 a short stroke and high lift, 3 the shortmovement toward the belt and a chance to adhere and cling to its surface. This upward movement decreases toward the tail end of the the cam N, causing a quick backward or downward movement of arms U. This drop of frame causes the sand to be thoroughly separated from the metal, and causes it to be thrown or raised into the current of water, while the metallicportions, on account of greater specific gravity, but principally on account of their 1y slightly released from the belt and are not raised into the water-current. Their release is sufficient, however, to cause them to travel forward on the belt-surface independent of any This independent forward travel is due to the greater speed of belt travel on the back stroke. The distance of 4 5 represents the hypotenuse on the upstroke, and the distance 5 6 4 on the back or downstroke. The gangue-tailings travel downward and wash off over drum G. i The concentrates travel upward and off the belt over drum E, and are brushed or scraped into box X by means of belt-wipers xx. The belt speed is regulated by means of cone-pulleys V V, thereby regulating speed of wormj and worm-wheel J.
